Speed response and measurement


Speed laws


Thermal activation

Reaction and measurement of rate


Notion of rate of chemical transformation, define the overall rate of a reaction,


Relate rate and variation in concentrations, quantities of matter or partial pressures for a closed reactor, define the transit time


stoichiometric equation and overall reaction rate
